相沢 ちえみ

24 years old. She works as an office worker for modestly sized company. She is a sports loving woman who is not afraid of talking and is well-liked by others for her cheerful and refreshing personality. She is very energetic due to her background in athletics.

Her current office job, which does not require much physical activity makes her feel restless and this mundane life is not enough for her. She has been looking for adventure and a boyfriend to fix this. She has never been able to have a relationship with a man due to her personality being way too easygoing.

She is still a virgin, although she is interested in sexuality in a way that is appropriate for her age. She then meets Asami, a sophisticated big sister, at the gym she goes to. They hit it off and together, they partake in a variety of hobbies.
